Final answer:
In psychological research reporting, personal anecdotes are unnecessary; however, research methods, statistical analysis, and results and conclusions are essential for an objective and reliable scientific report.
Step-by-step explanation:
When psychologists report the findings of a study in a scientific journal, it is important that they include a description of the research methods used, the statistical analysis, and the results and conclusions. The option that does not need to be included in a scientific report is c) Personal anecdotes.
Scientific reports require a clear and thorough explanation of the study, including how data was collected, which methods and techniques were employed, the way measurements were made, and the types of statistical analyses used to examine raw data. This allows for the replication of results by other researchers, enhancing the credibility and verifiability of the findings. Details such as research methods ensure that the study is reproducible, while the statistical analysis and results enable other scientists to understand the significance and implications of the research. Personal anecdotes, however, are not based on empirical evidence and cannot be generalized or reliably duplicated; thus, they do not belong in scientific reporting. It is crucial to exclude any subjective or anecdotal content to maintain the objectivity and rigor expected in scientific research.
